cf00349b5b Gave CvSVM a private copy constructor & assignment operator. 
The implicitly generated ones don't work properly, and I don't want to
write proper ones. :-)

4143071e22 In CvBoost, delegated update_weights's implementation to a helper method. 
This allows subclasses of CvBoost to override initial weights that
update_weights uses without duplicating its entire implementation.

7cab6798c0 Added two kernels to existing SVM framework 
Histogram intersection kernel (accessible by using SVM::INTER in CV namespace as kernel_type)
Exponetial chi2 kernel (accessible by using SVM::CHI2 in CV namespace as kernel_type)

Formulars:
Exp-CHI2
k(x,y) = exp(-gamma * CHI2(x,y))
CHI2(x,y) = 1- 2* SUM_i[(xi-yi)²/(xi+yi)]

Intersec
k(x,y) = SUM_i[min(xi,yi)]
